Not one of you guys have talked about OLD componets!
I still have WW2 surplus powder that they named H4831. It came in 50 pound kegs and cost about $20 a keg. I still use it, just last week I loaded and shot some in my 243. Still works perfect.
I have RWS primers that I purchased in the mid 1960s. The only reason I still have some is because RWS are really good primers and I have nursed them along over the years, for special occassions.
Some of my Norma powder also probably dates back to the 1960s. Still works perfect.
I still have some Herters powder which I have recently been successfully using. Many of you guys have probably never even heard of Herter's powder.
Fellows, you have a lot to learn about the shelf life of reloading compnents and loaded ammunition.
Bruce, you cheapskate. My 50 pound kegs of 4831 cost me $22 in 1970 at Ed Karrer's Gunnatorium in Milhaven. I have about 5 pounds of that powder left, along with a couple of thousand red and green packaged CIL large rifle primers. All work just fine.
Some of the Higginson's surplus powder didn't fare as well though. Had to scrap about 10 pounds of the #44 powder and a 7lb box of N160 that started sweating and clumping.
The #44 powder became quite unstable and corrosive, causing the cans to rust inside and a bore in a lovely little Mod 70 FWT, 257 Rob to rust when I put it away for a week, without cleaning it.
Look at the power. If it has an acidic smell or has rust colored dust in it you can expect it to be bad. If it's a nice shiney grey, it should be fine.
This is off topic but I picked up some powder from an auction many years ago and all of it was packed in a wooden box in 1lb cans. I didn't notice it at first, but all of the cans had the paint rubbed off in certain areas and the cans on the outside of the box had actually left indentations in the wood, as deep as the rolled seams on the top an bottoms of the cans. The base boards had indentations worn in them from the bottom edges as well.
I bought this stuff for a couple of bucks/pound.
It was H4895 and a powder I used a lot at the time.
Anyway, when I poured it into the reservoir on the throw measure, it looked a bit dull in appearance. No smell, no rust colored dust but there was dust, which is unusual.
Not really having much experience at the time and being a naturally cheap bastard, I was bound and determined to use the powder.
H4895 is a mid range powder and suitable for the 30-06, 303Brit and the 8x57 Mauser, along with others in that range. Very forgiving and consistent as well.
Well, I loaded up fir my old P17 a batch of surplus brass, with 165 grain bullets to while away a cold night and took them out to shoot on my next days off. WOW is a polite term. That stuff was hot as hell, even though the loads weren't anywhere near maximum.
The primers were not just flattened, but perforated and smeared. I shot two rounds just because and called it quits. Didn't even bother to check the target. My buddy finished it off. Cheap bastard as well.
It turns out that all of the powder was a write off. The fellow that put it up for auction, had stored it on a shelf in a small warm room, over a 25hp, dual lung compressor, mounted on a wooden floor. The powder was there for years and when he retired, he gathered up the powder along with a bunch of other stuff that didn't sell with the shop and put it up for auction.
At the time, PO Ackley was still alive and well and as I had met him, I gave him a call to explain the situation, still to cheap to throw away several pounds of powder.
He had run across similar situations before. The graphite coating on the granules had been worn off by the constant vibrations from the air compressor and as these coatings control burn rates, the powder was no longer safe, consistent or viable. He suggested I burn it. He also suggested that I was lucky I didn't get to wear part of that P17.
Now that is an extreme situation and not likely to happen to most people. Especially not to the OP but it is relavent and something to watch for.
